Gen 3 19 jhp ftf problems

[XDJYo]

Range trip with 2001 vintage G19 (3d gen) and my six 10 round mags of similar vintage. Three with factory 2183, three with 9mm3 followers I swapped in which Glock sent me. Ammo tested, Blazer FMJ and three various HP's laying around.

Test 1: Load one FMJ in each mag, insert into Glock with slide closed, hand rack the slide. Result - all fed fine.

Test 2: Repeat test 1 but with three different types of HP. Result - with 2183 all failed to load (impacted feed ramp). With 9mm3, all fed fine.

Thus, with HP as first and only round in mag, 100% feed failure with 2183 when hand racking the slide. Now to repeat this but attempt to load with action cycling from firing:

Test 3: Load two FMJ in each mag, insert into Glock with slide closed, hand rack the slide, fire. Result - all fed and fired fine.

Test 4: Repeat test three but first load one HP, then load one FMJ. Result - all mags loaded and fired the first round fine. The mags with 2183 experienced 100% failure to feed the HP round. The mags with 9mm3 fed the HP's just fine.

Conclusion: 2183 doesn't work with HP when HP is the first round loaded into a mag, regardless if attempting to load that round from hand racking the slide or from live firing a preceding round. Results may be different with any G19's that may have had manufacturing changes since 2001.

My assessment - the 9mm3 surface is similar to the surface of a round beneath it, so rounds on top of other rounds are basically feeding the "same way" as when the last round rides on the 9mm3. With the 2183 follower, the round on top of it does not have a constant surface to ride and that may be the problem. I'm guessing the round's nose doesn't stay elevated on the last round which doesn't seem to be a problem for FMJ, but for HP's flat nose it catches the base of the feed ramp.

One thing to be careful of with the 9mm3 follower-Some of us have had problems with feeding either FMJ or JHP on rounds 5-6 on a consistent basis. I would hit the range and test thoroughly with a few full mags of each bullet design/type/brand. That's the only way to be sure. It's one thing to have a surprise malfunction on round #10, but another on round #5 or 6.

Happy shooting and be safe!

Good advice, thank you - will test that next outing. It would be worse for rounds 5/6 to misfeed than round 10.



If 5/6 were to misfeed, I would probably go back to 2183 and just always make sure first round loaded is FMJ as Dimitri A. suggested. Or, is this why some are suggesting 9mm6?

Yes.

Keeping the 2183 followers you get reliable feeding of FMJ and JHP with the exception of the very last round fed from the mag. So, rounds 1-9 can be JHP and round #10 an FMJ. Nice easy solution especially for home defense.

9mm3 gets unreliable FMJ and JHP in the middle of the mag. Not a very good option.

9mm6 is supposed to fix all feeding for FMJ and JHP. Only drawback is that you have to modify either the follower or magazine.

My comments above are not gospel, just my observations with the wife's Glock and gathered from other comments here.

Happy shooting and be safe.

^^ I am sure Glock as a manufacturere is heart broken.



If the side of your gun says 9mm, it means it is designed for the 9mm Nato round. Glock and/or other manufactureres can not test nor do they care if the gun and the mags do not function 100% with every super zapper, zombie killing, apoclyptic preventor JHP or other tacticool ammo that is pouring into the market these days.

One can sue anyone for just about anything but it won't go too far without merit.

Not sure your point. The failure is induced with no rounds loaded at all if you understand the issue well enough to realize the follower getting stuck is not acceptable.

Beyond that I'm specifically talking about a common and well respected LE round, not the latest tacticool innovation.

But feel free to chime in like you know things, it's very impressive.

I pulled out my Dremel and sanded down the 9mm6 follower. The slide locked back on the last round, and did not get FTF.

Similar to this ^^^ solution.

I decided to keep the 2183 followers as they have the greatest track record and seem to be the most reliable known option with a variety of ammunition, both FMJ and JHP. I will wait for an official Glock fix to the existing magazines or replace them with a new updated magazine that resolves the issues (Magpul G19 10 round anyone?). Until then, I've decided to run all Corbon Pow'RBall +P as my HD round. Lacking Corbon availability, I'll use the solution option above or with a last round being Pow'RBall or a standard FMJ.

That's my HD choice for now. YMMV

I have a new G19 and 5 new Gen 4 mags (10 round) with the 2183 followers, and they all worked fine with JHP ammunition, maybe some people got defective mags? the last rd also feeds like normal.

Sig V crown JHP

Remington JHP

Hornandy JHP

Even the free mags Glock sent me didn't work. I think it's the guns themselves that are picky about the 10 round mags and followers.

I have since moved to Detroit and haven't had any issues while using standard capacity 15 round Glock factory magazines. In fact, I just used it for my CCW class without one single malfunction.

Glock's 10 round reduced capacity magazines have a lackluster reputation for reliability...

Bingo--the neutered 10 rd Glock 9 mm magazines for the G17 and G19 don't work consistently and reliably as we documented in two previous tests and as even Glock themselves state in their Armorer classes.
